In that case, let me apologize more sincerely. You really didn't deserve the abuse I piled on you over the past few days, and you've handled this difficult situation with grace. I disagree strongly with some of your viewpoints, but that certainly does not give me any right to talk to you like I did. I should've expressed my disagreement entirely in the form of logical arguments and not let things get personal. The failing here is mine, and I am sorry for it.

Piero,

I have been away for a few days.

Thank you for the apology.

I will try as hard as I can to write to clearly to avoid the possibility of unintentionally causing offense.
